An electronic device housing with a seemless user input zone that measures the level of force applied by the user is described. It is particularly advantageous when used with small hand-held consumer electronic devices such as mobile phones, PDAs, game-and media players. A housing for an electronic device includes a seamless user input zone defining a contact force-sensitive deformable area. A capacitance sensor is formed between the conductive inside surface of the housing and the electrode of the rigid base facing that inside surface. Linear support means such as columns support the housing away from the rigid base defining an air gap. Capacitance measurement circuit is deployed to detect the location and progressively increasing levels of force applied by the user onto the housing and send a user input signal to the electronic device.
